Multimeter is a simple command line application for GNU/Linux that ( hopefully :) ) reads values from a digital multimeter using the serial interface.

DMMs that are known to work:

It maybe works with similar multimeters too.

The DMM should send it's data like that:

600 or 1200 bps, 7 data bits, 2 stop bits, no parity

   Byte     0 1 2 3 4 5 6 7 8 9 A B C D 
   Ex. 1    D C - 1 . 2 3 4 5   V     \r
   Ex. 2          1 . 9 9 9 9 M o h m \r

Multimeter is free (see COPYING)

Just type 'make' and check if it works for you.

'multimeter -h' displays a little help message.

When the output is written into a file a HUP signal can be used to close and reopen the file (usefull for logrotates).

Send any comments, patches or what ever to Martin Hammerschmid <>.

I'm also interested if works with other multimeters.
